How does daylight saving time affect the safety of Britain's roads ? : an interim examination of crash and casualty trends around clock changes.

There has been considerable discussion over many years and in many countries about the impact Daylight Saving Time DST changes have on road risk, and how casualty reduction may be effected by altering the way in which DST is applied. This interim report sets out to inform the debate by examining the impact of DST changes on reported crash and casualty figures in Britain over the last six years. It forms the prelude to more detailed analysis which will be released at a later date. It focuses exclusively on hard evidence for consequences of the current DST regime, and does not address the issue of what effects any future changes may have. (Author/publisher)
